Identification of hexaploid synthetic wheat resistant to diseases

摘要

The evaluation of synthetic hexaploid wheat (HSW) conducted on the experimental fields of the Kazakh Research Institute of Farming and Plant growing according to generally accepted methods in plant pathology and plant growing. The germplasm accessionsoriginated from six winter durum wheat parents and lOaccessions of Aegilopstauschiihom Azerbayjan, Iran and Russia. The most superior lines were characterized by resistance to stripe rust, common bunt, tall structure (110-120 sm), big size of grain andspikes, and higher productivity comparative with commercial wheat cultivars. For leaf rust 16 out of 33 lines of HSW showed resistance and moderate resistance, 11 lines were moderate susceptible 6-24, 3 lines were susceptible to leaf rust (25-50). Forstripe rust 15 out of 33 lines of HSW showed resistance, 5 lines showed moderate resistance, 7 lines - moderate susceptible 10-40, 3 lines were susceptible to stripe rust (50-60).
